I believe gp’s point is that whether the recruiter is secret police doesn’t change much if NK decides to let its citizen do it in interviews.

It’s not like the “candidate” is doing that on their own. They’re most likely part of some branch of the military with a chain of command, a bunch of reports to fill, etc. So doing that in a pre-approved way is not unimaginable. Because, if they can pull this off (and the Lazarus hacks) one thing they’re not is dumb.
